With the goal of confirming the metallicity "excess" present in stars with planetary-mass companions, we present in this paper a high-precision spectroscopic study of a sample of dwarfs included in the CORALIE extrasolar planet survey. The targets were chosen according to the basic criteria that 1) they formed part of a limited volume and 2) they did not present the signature of a planetary host companion. A few stars with planets were also observed and analysed; namely, HD 6434, HD 13445 (Gl… 
Analysis of the Chemical Composition of the Atmospheres of Stars with Debris Disks and Planetary Systems
Spectroscopic studies of seven low mass stars in spectral classes F, G, and K are presented. Four of these (HD 1581, HD 10700, HD 17925, and HD 22484) have debris disks and for two of them (HD 22049
The abundance distribution of stars with planets
We present the results of a uniform, high-precision spectroscopic metallicity study of 136 G-type stars from the Anglo-Australian Planet Search, 20 of which are known to harbour extrasolar planets
The HARPS search for southern extra-solar planets XXXV. The interesting case of HD 41248: stellar activity, no planets?
Context. The search for planets orbiting metal-poor stars is of utmost importance for our understanding of planet formation models. However, no dedicated searches have been conducted so far for very
Chemical abundances of 451 stars from the HARPS GTO planet search program - Thin disc, thick disc, and planets
We present a uniform study of the chemical abundances of 12 elements (Si, Ca, Sc, Ti, V, Cr, Mn, Co, Ni, Na, Mg, and Al) derived from the spectra of 451 stars observed as part of one of the HARPS GTO
On the Nature of Stars with Planets
We consider the metallicities and kinematics of nearby stars known to have planetary-mass companions in the general context of the overall properties of the local Galactic disk. We have used
Parent Stars of Extrasolar Planets. VII. New Abundance Analyses of 30 Systems
The results of new spectroscopic analyses of 30 stars with giant planet and/or brown dwarf companions are presented. Values for Teff and [Fe/H] are used in conjunction with Hipparcos data and Padua
Spectroscopic metallicities for planet-host stars: Extending the samples
We present stellar parameters and metallicities for 29 planet-host stars, as well as for a large volume-limited sample of 53 stars not known to be orbited by any planetary-mass companion. These stars
Spectroscopic characterization of a sample of metal-poor solar-type stars from the HARPS planet search program
Stellar metallicity strongly correlates with the presence of planets and their properties. To check for new correlations between stars and the existence of an orbiting planet, we determine precise
Are Stars with Planets Polluted
We compare the metallicities of stars with radial velocity planets to the metallicity of a sample of field dwarfs. We confirm recent work indicating that the stars-with-planets sample as a whole is
Abundance Analyses of 12 Parent Stars of Extrasolar Planets Observed with the SUBARU/HDS ∗
High S/N ratio (350–600) and high resolution (R ∼90000) spectral data covering the wavelength region between 4200–8800 u A were obtained for 12 planet-harboring stars with the SUBARU/HDS. Detailed

Evidence for planet engulfment by the star HD82943
TLDR
The discovery of 6Li in the atmosphere of the metal-rich solar-type star HD82943, which is known to have an orbiting giant planet, can probably be interpreted as evidence for a planet (or planets) having been engulfed by the parent star.

TLDR
A spectroscopic orbit with period P=3.52433+/-0.00027 days for the planetary companion that transits the solar-type star HD 209458 is reported, based on a new analysis of the iron lines in the HIRES template spectrum and also on the absolute magnitude, effective temperature, and color of the star.
